    Design and Implementation of an Electrostatic

    An Electrostatic Precipitator (ESP) is a device that is used to remove and collect the particles from a flue gas by using the force of an induced electrostatic charge from a high voltage power supply unit. This is the most efficient way to solve the pollution problem as a result of wood combustion [3, 4]

    An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.. In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and

    the precipitator voltage was modulated, initially by hand wheel, then by a motor drive as automatic voltage optimisation systems were introduced. To limit short circuit currents primary resistance or inductance was added to the transformer to increase the total impedance. Later, control was by the use of magnetic saturable reactors or transductors
